Looks good. Nice damage too. If you can buy mapp gas and use that instead of propane you'd get a little better preformance. Also (if) you can get a stun gun and make multiple spark gaps that would increase preformance... and everyone wants moar power...

Well, I can't really see much from the pictures. Any chance of getting some better ones?

As for as for what you said, multiple sparks can be accomplished with a simple piezo igniter. Simply wire them in series. The width of all of your gaps shouldn't exceed the maximum distance your piezo igniter can easily jump.

How many sparks can a piezo generate? I have heard people said only 2 but if i can can away with more it would be great.Also, as of right now my spark is located in the front of the chamber towards the breach where there is a double layer of pvc. Is it safe to screw in screws for another spark in the middle of the chamber despite only one layer of pvc?Here are some more pics....
